Sunrise Blooming is a snarky, pessimistic fellow. He's hardly more than a teenager, and he acts like it. He's the youngest wolf in the hunting party and has to be kept in line by his fellow packmates. Complaining is one of his hobbies, and he'll often pick fights just to burn off some of his energy or alleviate his insecurities. He rarely means true harm, however; at his heart, Sunrise is a fiercely loyal wolf and loves his pack.
Sunrise Blooming pins his ears as you approach, stalking away from you. As the pale fur along his back begins to bristle, you wisely choose not to follow. One of his other packmates steps in to nip him for you. That should teach him not to be so rude to guests!
